Maybe the plastik part of the door is too far away from the switch so it won't be pushed in far enough ? Test it by sticking something on the plastik part with tape (is it still there ?) with one, two ore some more millimeters (40,80...mills). But the question is - why doesn't the door push the switch correctly ? Is it installed correctly ? is it the correct switch ? Can you take a picture ? I always have the inverse problem with my other car, where the contacts are corroded.... Elvis...with great door lights in his 6548 I have the most frustrating door lights of all time.....I can sit there a million times and push the little door light/door ajar button and the lights go out instantly. As soon as I close the door, the lights stay on!!!!!....Is this magic? Obviously the door closing shut is not pushing that little knob at all or maybe somehting is shorting somewhere...
